Lake City, Utah, 1965, relating to the Uniform Building Code by adding to
said Chapter a new section 5-1-20 relating to special provisions for High
Rise Group H Occupancies and Group F Division 2 Office Buildings.
Be it ordained by the Board of Commissioners of Salt Lake City, Utah:
SECTION 1. That Chapter I, Title 5, Revised Ordinances of Salt Lake
City, Utah, 1965, relating to the Uniform Building Code be, and the same
hereby is, amended by adding to said Chapter a new section 5-1-20 relating
to special provisions for High Rise Group H Occupancies and Group F Divi-
sion 2 Office Buildings to read as follows:
Section 5-1-20. Special Provisions for High Rise Group H Occu-
pancies and Group F Division 2 Office Buildings
Chapter 18 of Volume I Uniform Building Code, 1970 Edition, is
amended by adding thereto a new section 1807 to read as follows:
Section 1807. Special Provisions for High Rise Group H Occu-
pancies and Group F Division 2 Office Buildings.
(a) Scope
These requirements apply to buildings housing Group F
Division 2 Occupancies used as offices and to Group H
Occupancies.
Such buildings having floors used for human occupancy
located more than 75 feet above the lowest level of
Fire Department vehicle access shall conform to the
requirements of this Section in addition to other appli-
cable requirements of this Code.
(b) Compartmentation
1. Compartmentation shall be provided in every build-
ing to provide areas of refuge for the building
occupants. This may be provided by:
a. Installation of horizontal exists dividing a
story into two or more areas of approximately
the same size not exceeding 30,000 square feet,
or
b. Sub-dividing the building into 5 story compart-
ments by interrupting the stairshaft with smoke
barriers every 5th floor or through the use of
smokeproof enclosures for all stairways or any
other method which will protect against the
movement of smoke from one compartment to another.
2. Openings in exterior walls located vertically above
-2-
one another shall be protected by approved flame
barriers extending 30 inches beyond the exterior
wall in the plane of the floor or by vertical
panels not less than 3 feet in height.
3. When compartmentation is by a horizontal exit, there
shall be no openings in the separating wall which
would permit transfer of smoke through the wall ex-
cept for the required exit.
(c) Fire Alarm
A manual fire alarm box shall be located adjacent to
exits into stairway shafts and in every elevator lobby.
The box shall be connected to the Central Control Sta-
tion and to the voice communication system as required
by Sections 1807 (f) and (g). The system shall be de-
signed in accordance with UBC Standard No. 18-1 (to be
based upon applicable provisions of NFPA 71, 72A or 72B).
(d) Fire Detectors
An approved system which will provide for automatic
detection of products of combustion other than heat
shall be installed in every mechanical equipment room
and in the return air portion of every air conditioning
and mechanical ventilation system that serves floors
other than the floor on which the equipment is located.
Detectors set to operate within the limitations of UBC
Standard No. 43-6 or for greater sensitivity shall be
located at each opening into the vertical shaft.
(e) Voice Alarm System
Both the detection system and the fire alarm system shall
activate a voice alarm system capable of being operated
from the Central Control Station on both a general and
selective basis and dependent upon the compartmentation
involved. The alarm shall be designed to be heard by
all occupants within the building or designated portions
thereof and within elevators. The elevator lobby de-
tector required by Chapter 51 shall be connected to the
system.
(f) Voice Communication System
There shall be two separate approved continuously elec-
trically supervised voice communication systems; one for
Fire Department communication system and the other a
public voice communication (address) system between the
central control station and the following areas:
1. Elevators, elevator lobbies, corridors and stairways.
2. Every office area exceeding 1,000 square feet in
area.
3. Each dwelling unit and hotel guest room. When
approved, the fire department system may be com-
bined with the public voice communication system.
(g) Central Control Station
A central control station for Fire Department operations
shall be provided in a location approved by the Fire
Department. It shall contain the voice communication
systems panel; fire detection and alarm system panels;
status indicators and controls for elevators and air
handling systems, a public telephone and sprinkler
valve and water flow detectors and standby power controls.
-3-
(h) Smoke Control
Natural or mechanical ventilation for the removal of
the products of combustion shall be provided in every
story and shall consist of one or more of the following:
1. Panels or windows in the exterior wall which can be
opened from an approved location other than the fire
floor. Such venting facilities shall be provided
at the rate of at least 20 square feet per 50 lineal
feet of exterior wall in each story, and distributed
around the perimeter at not more than 50 foot inter-
vals. Such panels shall be clearly identified as
required by the Fire Department.
2. Tempered glass may be used in lieu of openable
panels.
3. When fire sprinklers are installed in compliance
with Section 1807 (m), the mechanical air handling
equipment may be designed to assist smoke removal.
Under fire conditions, the return and exhaust air
shall be moved directly to the outside without re-
circulation to other sections of the building.
4. A shaft through which smoke and heat can be mech-
anically vented to the outdoors. The size of the
shaft shall be uniform throughout and of such
dimensions as to provide 60 air changes per hour
in the largest compartment served anywhere in the
building. Openings into the shaft shall be pro-
- tected with an automatic single piece shutter
located as high in the room as possible and designed
to vent the entire compartment.
5. Any other design which will produce equivalent
results.
(i) Elevators
At least one elevator in each bank available for Fire
Department access to any floor shall be provided. The
elevator shall open into a lobby, which may serve addi-
tional elevators, and shall be separated from the re-
mainder of the building by construction as required for
corridors. The elevator may be within a smokeproof en-
closure. See Chapter 51 for additional requirements.
In addition to the above requirements, an automatic
elevator override system shall be installed to prevent
a car from stalling at fire floors for protection of
the occupants of the elevator and to enable firemen to
have access and full control of elevators during an
emergency.
(j) Standby Power and Light
A permanently installed stand-by power generation
system conforming to UBC Standard No. 18-1 (to be based
on NFPA 70-1971) shall be provided. The system shall
be equipped with suitable means for automatically
starting the generator set upon failure of the normal
electrical service and for automatic transfer and opera-
tion of all required electrical functions at full power
within sixty seconds of such normal service failure.
System supervision with manual start and transfer
features, shall be provided at the Central Control
Station.
a.,
-4-
An on-premise fuel supply sufficient for not less than
two hours full demand operation of the system shall be
provided. All power, lighting, signal, and communica-
tion facilities provided under the requirements of this
section shall be transferable to the stand-by power
system.
The power requirement shall be determined so as to pro-
vide service to, but not limited to the following:
1. Fire alarm system.
2. Exit and other emergency lighting.
3. Fire protection equipment.
4. Mechanical ventilation required by this section.
5. Fire Department elevator.
6. Voice communication system.
(k) Seismic Considerations
In Seismic Zones 2 and 3 the anchorage of the following
mechanical and electrical equipment required by the
section shall be designed in accordance with Section
2314 for a lateral force based on a "Cp" value of 0.5
unless data substantiating a lesser value is furnished:
1. Elevator drive and suspension systems.
2. Standby power and lighting facilities.
3. Fire pumps and other fire protection equipment.
(1) Exits
All stairway doors which are to be locked from the
stairway side shall have electric strikes which can
be automatically unlocked upon a signal from the Central
Control Station.
Emergency telephones shall be provided at not less than
every fifth floor in each required stairway.
(m) Fire Sprinkler Alternative
Sprinkler protection conforming to the following may
be provided as an alternate to compartmentation:
1. The sprinkler system is hydraulically designed using
the parameters set forth in UBC Standard No. 38-1
(to be based on Chapter 8 of NFPA 13-1972) and the
following:
a. Shut off valves and waterflow devices shall be
provided on each floor. In addition to actuating
a local alarm on the floor upon which the water
flow is detected, such valves shall be supervised
by a continuously manned control station or by a
central station.
b. The sprinkler system shall be looped between
standpipe risers at the bottom, top and mid-
height of all buildings with a maximum of 20
stories served by any loop. At each loop level
there shall be check valves.
c. Piping may be copper or steel with no minimum
size of pipe required. Solder connections may
be used if not less than 95 percent tin and 5
percent antimony.
d. Pitching of lines is not required.
-5-
e. A minimum of 2 fire pumps independently driven
shall be provided and sized for the sprinkler
demand and for a minimum 500 gallons per minute
Fire Department standpipe operations.
f. An on-site supply of water equal to a 20 minute
demand or 15,000 gallons on a combined sprinkler
and standpipe, whichever is the smaller, shall
be available automatically if the principal
supply fails.
If a swimming pool is used as the on-site water
supply said pool shall be filled year round and
shall be constructed so as to comply with the
applicable provisions of section 2314 of this
Code. In addition, such pool must be covered
in winter and so constructed and equipped to
prevent freezing of the water supply.
g. Operation of the sprinkler system shall activate
the voice communication system.
2. When the automatic sprinkler system described above
is installed, the following reductions from this
code are permitted:
a. The fire-resistive time periods set forth in
Table No. 17-A may be reduced by one hour for
interior bearing walls, exterior bearing and
non-bearing walls, roofs and the beams support-
ing roofs provided they do not frame into columns.
All office building partitions required to be of
one-hour fire-resistive construction by Table No.
17-A and Section 3304 (g) may be of non-combust-
ible construction without a fire-resistive time
period. Openings in corridor partitions shall
be protected by tight fitting, self-closing doors
that need not have a fire-resistive time period.
In Group H Occupancies, corridor and dwelling
unit or guest room separation may be reduced to
one-half hour.
b. The one and one-half inch hose lines and nozzles
may be omitted.
c. Travel distance to a horizontal exit or to an
enclosed stairway may be 300 feet.
d. Smokeproof enclosures may be eliminated if each
required stairway is pressurized as provided in
Section 3309 (h) to .15 inches of water column.
e. Spandrel protection required by Section 1807 (b)
may be omitted.
SECTION 2. In the opinion of the Board of Commissioners of Salt
Lake City, it is necessary to the peace, health and safety of the inhabitants
of Salt Lake City that this ordinance become effective immediately.
SECTION 3. This ordinance shall take effect upon its first pub-
lication.
